Abstract
In view of the problems of blue plume and excessive particulate matter in the flue gas discharged from of the 1.2 million t/a heavy oil fluid catalytic cracking unit of Lanzhou Petrochemical Company of PetroChina Natural Gas Co.,Ltd.,the industrial application tests of the caustic soda desulfurization and de-bule technology were carried out.The effects of this technology on blue plume elimination and particulate matter removal were systematically studied,and its effects on wastewater quality and operating cost were analyzed,and the existing problems and optimization directions of the industrial application unit were discussed.The results showed that continuous dosing of solid caustic soda could completely eliminate the blue piume.The emission concentration of flue gas particulate matter was reduced to 4.39-12.70 mg/m3,which met the emission standard requirements of particulate matter concentration≤30 mg/m3 specified in GB 31570-2015 Emission Standard of Pollutants for Petroleum Refining Industry.The consumption of NaOH was reduced by 20%-30%,and the injection of sulfur transfer agent was stopped.The daily operating cost was decreased by about 9380 yuan.This technology provided an effective solution for flue gas purification of fluid catalytic cracking units.关键词
